4 Claims.

An object of the invention is to provide an improved securing means.

Another object is to provide an improved securing means which will besimple in construction and application.

Another object is to provide an improved securing means which will beeconomical to manufacture.

Another object is to provide an improved securing means which willeffectively hold parts together.

Another object is to provide an improved means of deflecting light whichwill be simple and effective.

Another object is to provide an improved means of deflecting light whichmay be readily adjusted.

Other objects will hereinafter appear.

The invention will be better understood from the description of onepractical embodiment thereof, illustrated in the accompanying drawing,in which;

Figure 1 is a perspective view of a lamp shade or reflector having alight deflecting extension secured to it, the extension and securingmeans constituting one embodiment of the invention; and

Figure 2 is a fragmentary sectional view of the parts illustrated inFigure 1, showing the manner in which the deflector is applied andsecured.

A more or less conventional lamp socket is illustrated at I, it beingprovided with an incan descent electric light bulb 2. Carried by thesocket is a shade consisting of a neck 3 and an outwardly flaringportion 4 which terminates in a peripheral annular bead 5. Thisreflector may be of any desired material, as glass, porcelain, metal, ormetal coated with enamel, such as the shades or reflectors in more orless common use at the present time.

Ordinarily, such reflectors are of insufilcient depth to completelyconceal the incandescent bulb, but while they reflect considerable lightemanating from the upper portion of the bulb, they permit rays toemanate directly from the filament thereof past the shade, illuminatinga zone substantially greater than a hemisphere.

Thus, when a shade is arranged with its margin in horizontal position ateye level, or even somewhat below this level, rays passing directly fromthe bulb reach the eye. When the shade and bulb are arranged over anarticle to be illuminated, light coming from the bulb directly to theeye of the observer subjects his eye to a considerable strain.

If rays reach his eye only after being reflected by the object which itis desired shall be illuminated, not only is this strain reduced, butthe object can more clearly be perceived.

To obtain this advantage, I have provided a screen or deflector whichmay be applied to a portion of the periphery of the shade and which willprevent any direct rays from the incandescent light source within theshade reaching the eye of an observer.

This screen or shield is shown as an arcuate cylindrical plate 6, havinga beaded upper edge 1 capable of overlying the peripheral bead 5 of theshade.

Through the plate are provided a series of perforations 8 adjacent thisupper edge, and for each perforation is supplied a clip convenientlymade of resilient material such as metal wire, having an offset upperend as indicated at 9 terminating in a hook Ill, an intermediatesubstantially straight shank H, and a lower end or detent l2.

The clip is inserted in the position indicated in dotted lines in Figure2, and then is swung downwardly into the position shown in full lines inthis figure, where its lower end I2 is snapped under the lower edge ofthe deflector. Due to the resiliency of the wire, it maintains pressureupon the lower edge of the plate and also upon the inside of the bead ofthe shade, effectively se curing the deflector plate thereto.

Obviously, several of the clips may be used on each deflector plate, twoor three generally being sufiicient to securely hold the plate in place.

While I have described the illustrated embodiment of my invention insome particularity, obviously others will readily occur to those skilledin this art, and I do not therefore limit myself to the precise detailsshown and described, but claim as my invention all embodiments,variations and modifications coming within the scope of the appendedclaims.

I claim:

1. A light shield comprising an arcuate metal plate adapted to besecured to the margin of a shade, the plate having a curvedchannel-shaped edge shaped to embrace the edge of said shade, and meansengaging opposite surfaces of the edge of said shade holding said edgesin contact.

2. A light shield comprising an arcuate metal plate adapted to besecured to the margin of a shade, the plate having a curvedchannel-shaped edge shaped to embrace the edge of said shade,

and a plurality of clips detachably engaging said plate and arranged tocontact the opposite side of the marginal portion of said shade inalignment with said edge.

3. An arcuate cylindrical plate having a channel-shaped recessed edge, aplurality of holes through said plate adjacent said edge, a clipextending through each of said holes, each clip comprising a resilientmember having a hookshaped end projecting into the open side of saidchannel-shaped edge, a straight intermediate part lying closely adjacentthe surface of said plate, and a detent engaging the edge of said plateremote from said first mentioned edge.

4. In combination, a lamp shape having a channel-shaped edge, a shieldhaving a channelshaped edge overlying the edge of the shade, the shieldbeing provided with a plurality of apertures closely adjacent said edge,a clip extending through each aperture and having a hook-shaped endbearing upon the interior of the channelshaped edge of the shade, theclip extending downwardly below the remote edge of the plate,

and resiliently engaging this last mentioned edge 10 of the plate.
